ninject

I had a series of very bizarre errors being thrown in my repositories. Row not found or changed, 1 of 2 updates failed... Nothing made sense. It was as if my DataContext instance was being cached... Nothing made sense and I was considering a career move. I then noticed that the DataContext instance was passed in using dependency injection, using Ninject (this is the first time I have used DI...). I ripped out the Dependency Injection, and all went back to normal. Instantly. So dependency injection was the issue, but I still don't know why. I am speculating that Ninject was caching the injected

I have defined one interface and one class: public interface IRepository<T> { } public class RoleRepository:IRepository<Domain_RoleInfo> { } Inject here: public RoleService { [Inject] public RoleService(IRepository<Domain_RoleInfo> rep) { _roleRep=rep; } } How can I perform Dependency Injection With Ninject,say how to bind? I have written a helper class as below, it works fine with non-generic interface.but how to refactor it support generic interface as above? public class RegisterNinjectModule : NinjectModule { public override void Load() { BindServices(); BindRepositories(); } private void

I have inherited a Windows service where all the dependencies are created when the service starts and are injected in the transient scope. We are having a number of problems with this service, not least we have a DbContext which lives for the whole time the service is running, and different instances of it are injected each time. I would like to refactor so that each worker thread gets it’s own DbContext injected which will live for just the duration of each tick. I have looked at the custom scope . It looks fine for a single threaded app, but not multi-threaded. I also considered

i have the following interfaces injected in Castle Windsor. how do i do the same in Ninject? container.Register( AllTypes.FromAssemblyNamed("Apps.Web") .BasedOn(typeof(ICommandHandler<>)) .WithService.FirstInterface()); i've tried: this.Bind(x => x.FromAssembliesMatching("Apps.Web.dll") .Select(y => y.Namespace.EndsWith("Handlers")) .BindSingleInterface()); but getting Object reference not set to an instance of an object error. You can use Ninject's convention binding extensons (install it from NuGet ) to do this. Something like the following should work kernel.Bind(x => x

I am trying to set up a new project and I've added a new class MembershipService that requires the HttpContext to be passed in it's constructor. In a previous project I used the code private static void RegisterServices(IKernel kernel) { kernel.Bind<IMembershipService>() .To<MembershipService>() .InRequestScope() .WithConstructorArgument("context", HttpContext.Current); .... } However in the new project I'm using Ninject Modules, and after some searching on StackOverflow and Google, I've come up with the code below: public class ServiceHandlerModule : NinjectModule { public override void Load(

With NInject (preferably 2.0), what options do we have wrt wiring up our object dependencies in a web application? Can they be defined in an XML configuration file? Or does it have to be done via code? Ninject doesn't have XML configuration, sorry but I can't provide a direct link (cos their site has flash elements), but here is a quotation from ninject.org : Free yourself from XML Most other .NET dependency injection frameworks are designed around the use of XML to declare type bindings. Rather than forcing you to write cumbersome and error-prone text, Ninject arms you with a fluent interface

I'm having something like this: class Root { public Root(IDependency dep) {} } class Dependency:IDependency { public Dependency(int val) {} } And I'm trying to obtain a reference to Root using ninject. So i configure it like this var module = new InlineModule(mod => mod.Bind<IDependency>().To<Dependency>()); var kernel = new StandardKernel(module); I'd like to inject into Dependency some 'val' value that is known only at the moment of obtaining the Root reference from ninject. What i'd like to do is something like this: Kernel.Instance.Get<Root>(With.Parameters.ConstructorArgument("val", 12));
